Description

Technical Field

[0001] This utility model relates to the technical field of roller conveying devices, and in particular to a sprocket roller for conveying. Background Technology

[0002] The existing power roller conveyor uses a double-chain structure for transmission, which is complex. When a fault occurs and repair is needed, disassembly is cumbersome and maintenance is difficult.

[0003] The existing patent CN222361475U describes a single-sprocket powered roller mill, which includes a roller frame with several single-sprocket rollers spaced apart on the frame. Synchronous transmission between any single-sprocket rollers is achieved through the movement of a transmission chain. The roller frame has a guide bar structure supporting the transmission chain along its length. The transmission chain is connected to a sprocket group driven by a motor to achieve cyclic movement. The single-sprocket roller mill has a transmission chain on only one side. Its transmission method is simpler than that of a double-sprocket roller mill. This simple structure makes the single-sprocket roller mill easier to install and maintain, and also reduces the operating cost of the equipment.

[0004] In actual use, there may be instances where a single roller is damaged. However, when repairing a single roller, the existing equipment requires disassembling most of the parts on the machine body in order to remove the damaged roller, which makes it less practical. Utility Model Content

[0005] The purpose of this utility model is to provide a conveyor sprocket roller that solves the problem that existing equipment requires disassembling most of the parts on the machine body to remove the damaged roller when repairing a single roller, resulting in low practicality.

[0006] To achieve the above objectives, this utility model provides a conveying sprocket roller, including a body, a drive device, and a roller assembly. The drive device is installed inside the body. The roller assembly includes a mounting cylinder, a drive wheel, a connecting roller, an inner cylinder, an elastic member, an outer cylinder, and a fixing member. The mounting cylinder is rotatably connected to the body and located on the side of the body closer to the drive device. The drive wheel is fixedly connected to the mounting cylinder and located on the side of the mounting cylinder closer to the drive device, and is connected to the drive device. The connecting roller is slidably connected to the mounting cylinder and located on the side of the mounting cylinder away from the body. The inner cylinder is slidably connected to the connecting roller and located on the side of the connecting roller away from the mounting cylinder. The elastic member is installed in the inner cylinder and drives the connecting roller to move. The outer cylinder is slidably connected to the inner cylinder and located on the side of the inner cylinder away from the connecting roller. The fixing member is installed on the outer cylinder.

[0007] The roller assembly further includes a limiting plate and a driving roller. The limiting plate is slidably connected to the inner cylinder and is located on the side of the inner cylinder close to the connecting roller, and is connected to the connecting roller. The driving roller is slidably connected to the mounting cylinder and is located on the side of the mounting cylinder away from the connecting roller, and abuts against the connecting roller.

[0008] The elastic component includes a telescopic rod and a spring. The telescopic rod is fixedly connected to the inner cylinder and is located on the side of the inner cylinder away from the connecting roller, and is connected to the connecting roller. The spring is sleeved on the outside of the telescopic rod, and the two ends of the spring abut against the inner cylinder and the connecting roller, respectively.

[0009] The fixing component includes a fixing screw and a cap. The fixing screw is slidably connected to the inner cylinder and is located on the side of the inner cylinder away from the connecting roller, and is connected to the outer cylinder. The cap is slidably connected to the fixing screw and is located at the end of the fixing screw close to the outer cylinder, and is connected to the outer cylinder.

The drive wheel is fixedly mounted on the mounting cylinder and abuts against the drive device, allowing the drive device to rotate the mounting cylinder via the drive wheel. A connecting roller is slidably mounted within the mounting cylinder. The mounting cylinder has a groove that mates with the connecting roller, allowing the connecting roller to slide into the mounting cylinder and causing the mounting cylinder to rotate the connecting roller. An inner cylinder is slidably mounted on the connecting roller and also has a groove that mates with the connecting roller, allowing the connecting roller to rotate. The connecting roller can drive the inner cylinder to rotate. The elastic component is installed in the inner cylinder and drives the connecting roller to move, so that the connecting roller is stably located in the mounting cylinder, thereby allowing the inner cylinder to be installed on the machine body. The outer cylinder is slidably installed on the outside of the inner cylinder, so that the inner cylinder can drive the outer cylinder to rotate. The fixing component is installed on the inner cylinder, so that the outer cylinder can be more stably installed on the inner cylinder, thereby allowing the outer cylinder to drive the movement of items. This enables more convenient and faster installation and removal of damaged rollers, thus improving the practicality of the equipment. Attached Figure Description

Figure 2 This is a schematic diagram of the internal structure of the inner and outer cylinders according to the first embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the mounting cylinder according to the first embodiment of this utility model.

[0020] This utility model provides a conveyor sprocket roller, including a body, a drive device, and a roller assembly. The roller assembly includes an mounting cylinder 100, a drive wheel 101, a connecting roller 102, an inner cylinder 103, an elastic component, an outer cylinder 104, a fixing component, a limiting plate 105, and a drive roller 106. The elastic component includes a telescopic rod 107 and a spring 108. The fixing component includes a fixing screw 109 and a cap 110. The mounting cylinder 100 has a guide portion 111. This solution solves the problem that existing equipment requires disassembling most of the parts on the body to remove the damaged roller when repairing a single roller, resulting in low practicality.

[0021] In this specific embodiment, the drive device is installed inside the machine body. The machine body and the drive device are the roller frame and guide bar structure described in the existing patent technology CN222361475U, a single sprocket powered roller machine. The drive device is installed on the machine body and provides rotational power to the roller. This solution enables more convenient and faster installation and disassembly of damaged rollers, thereby improving the practicality of the equipment.

[0022] The mounting cylinder 100 is rotatably connected to the machine body and located on the side of the machine body closer to the driving device. The driving wheel 101 is fixedly connected to the mounting cylinder 100 and located on the side of the mounting cylinder 100 closer to the driving device, and is connected to the driving device. The connecting roller 102 is slidably connected to the mounting cylinder 100 and located on the side of the mounting cylinder 100 away from the machine body. The inner cylinder 103 is slidably connected to the connecting roller 102 and located on the side of the connecting roller 102 away from the mounting cylinder 100. The elastic member is installed in the inner cylinder. In step 103, the elastic member drives the connecting roller 102 to move. The outer cylinder 104 is slidably connected to the inner cylinder 103 and is located on the side of the inner cylinder 103 away from the connecting roller 102. The fixing member is installed on the outer cylinder 104. The mounting cylinder 100 is installed inside the machine body via bearings. The drive wheel 101 is fixedly installed on the mounting cylinder 100 and abuts against the drive device, thereby enabling the drive device to drive the mounting cylinder 100 to rotate via the drive wheel 101, and the connecting roller 102 slides. An inner cylinder 103 is slidably mounted on the connecting roller 102, having a groove that mates with the connecting roller 102, allowing the connecting roller 102 to slide into the mounting cylinder 100 and rotate. The inner cylinder 103 also has a groove that mates with the connecting roller 102, allowing the connecting roller 102 to rotate. A spring-loaded member is installed in the inner cylinder 103, driving the connecting roller 102 to move. The connecting roller 102 is stably positioned in the mounting cylinder 100, thereby allowing the inner cylinder 103 to be mounted on the machine body. The outer cylinder 104 is slidably mounted on the outside of the inner cylinder 103, enabling the inner cylinder 103 to drive the outer cylinder 104 to rotate. The fixing component is mounted on the inner cylinder 103, allowing the outer cylinder 104 to be more stably mounted on the inner cylinder 103, thereby enabling the outer cylinder 104 to drive the movement of items. This allows for more convenient and faster installation and removal of damaged rollers, thus improving the practicality of the equipment.

[0023] Secondly, the limiting plate 105 is slidably connected to the inner cylinder 103 and located on the side of the inner cylinder 103 close to the connecting roller 102, and is connected to the connecting roller 102; the driving roller 106 is slidably connected to the mounting cylinder 100 and located on the side of the mounting cylinder 100 away from the connecting roller 102, and abuts against the connecting roller 102. The limiting plate 105 is slidably installed at one end of the inner cylinder 103, and the limiting plate 105 abuts against the connecting roller 102, thereby placing the connecting roller 102 inside the inner cylinder 103. The connecting roller 102 can only move by pulling out the limiting plate 105. The driving roller 106 is slidably installed in the mounting cylinder 100, and the driving roller 106 passes through the mounting cylinder 100 and abuts against the connecting roller 102. The driving roller 106 drives the connecting roller 102 to move towards one end of the mounting cylinder 100, thereby allowing the inner cylinder 103 to be quickly removed.

[0024] Meanwhile, the telescopic rod 107 is fixedly connected to the inner cylinder 103 and located on the side of the inner cylinder 103 away from the connecting roller 102, and is connected to the connecting roller 102; the spring 108 is sleeved on the outside of the telescopic rod 107, and the two ends of the spring 108 abut against the inner cylinder 103 and the connecting roller 102 respectively. One end of the telescopic rod 107 is fixedly installed in the inner cylinder 103, and the other end of the telescopic rod 107 is connected to the connecting roller 102. The telescopic rod 107 limits the distance the connecting roller 102 can move in the inner cylinder 103, preventing the connecting roller 102 from sliding out of the inner cylinder 103. The spring 108 is sleeved on the outside of the telescopic rod 107, and the two ends of the spring 108 abut against the inner cylinder 103 and the telescopic rod 107 respectively. The elastic force of the spring 108 drives the connecting roller 102 to move, thereby causing the connecting roller 102 to be inserted into the mounting cylinder 100.

[0025] Additionally, the fixing screw 109 is slidably connected to the inner cylinder 103 and located on the side of the inner cylinder 103 away from the connecting roller 102, and is connected to the outer cylinder 104; the cap 110 is slidably connected to the fixing screw 109 and located at the end of the fixing screw 109 near the outer cylinder 104, and is connected to the outer cylinder 104. The fixing screw 109 is rotatably mounted on the inner cylinder 103. The inner cylinder 103 has a threaded hole that mates with the fixing screw 109, thereby allowing the fixing screw 109 to be fixed on the inner cylinder 103, and thus allowing the outer cylinder 104 to be fixed on the inner cylinder 103 by the fixing screw 109. The cap 110 is made of rubber and is mounted on the fixing screw 109, covering the hole on the outer cylinder 104.

[0026] Finally, the guide part 111 is located on the side of the mounting cylinder 100 near the connecting roller 102. The guide part 111 is provided at the end of the groove of the mounting cylinder 100. The guide part 111 enables the connecting roller 102 to slide into the mounting cylinder 100 even with a small error, thereby improving the installation efficiency.

[0027] Using a conveying sprocket roller according to this embodiment, during installation, the connecting roller 102 at one end of the inner cylinder 103 is first inserted into the mounting cylinder 100. At this time, the other end of the inner cylinder 103 is aligned with the mounting cylinder 100 on the other side. Then, the limiting plate 105 is pulled out, and the spring 108 drives the connecting roller 102 to move, so that the connecting roller 102 is inserted into the mounting cylinder 100, thereby fixing the inner cylinder 103 and the outer cylinder 104 to the machine body. When the roller is damaged, the connecting roller 102 is driven by the driving roller 106 to move away from the mounting cylinder 100, so that the connecting roller 102 leaves the mounting cylinder 100, thereby allowing the inner cylinder 103 to be removed. This enables more convenient and faster installation and disassembly of damaged rollers, thereby improving the practicality of the equipment.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
